It looks like I was too hasty.

It's now possible to load the amd-pstate driver via kernel-parameter... (since
when?)
I've just added amd_pstate.shared_mem=1 and that does the trick. And it seems
my CPU only accepts the option with shared-memory, even though it's Zen3.

���������kernel: amd_pstate: This processor supports shared memory solution, you can
enable it with amd_pstate.shared_mem=1���������

but it looks like this is not the end of the development yet?
